SPECIFICATION forming part of Letters Patent N0.'271,550, dated January30, 1883. Application filed August 26, 1282. (No model.)

1'0 all whom it may concern:

Be it known that we, HARDY E. TUPPER, WILLIAM TUPPER, and J OSEPH A.TUPPER, all of the township of Bury, in the county of Compton andProvince of Quebec, Canada, have invented certain new and usefulImprovements in Evaporators; and we do hereby declare'that the followingis a full, clear, and exact description of the same.

Our invention has reference to improvements in that class of evaporatorsused in boil-. ing sap for the purpose of converting the same intosugar, and may be described as consisting in a novel construction andarrangement of the apparatus, by which we are enabled to utilize everyparticle of heat from the fire and distribute the same throughout everyportion of the apparatusduring the operation, so as to produce betterresults, and in less time and with a greater economy of fuel than in thepresent arrangements, which will be readily understood by the followingdescription and by reference to the accompanying drawings, where similarletters of reference indicate like parts, and where- Figure l is alongitudinal section of our evaporator, taken through line 00 m, Fig. 3.Fig. 2 is a cross-section of same, taken on line y 3 Fig. 3. Fig. 3 is aplan view of same.

LetterA represents the main pan, arranged in the center of theapparatus, as shown, and of any size or configuration desired. This panis supported by the Walls a a of the fire-chamber, these walls beingpreferably slanting inward, so as to form an arch, as shown particularlyin Figs. 1 and 2, over the fire-chamber B.

A is the tire-door at the front of the firechamber.

On each side of the pan A and fire-chamber B we form chambers O D and EF, and at the back is arranged a chamber, G, and behind this again thesmoke-chamber H, to the upper side of the latter being connected anysuitable smoke-pipe, h.

In the partitionsbetween the chambers G and C and between C and D areformed openings 9 and 0, at the extreme lower part of same, and thechamber D is connected with the chamber E on the opposite side of thepan by a pipe, K, extending across the fire-chamber B, close to theground and just inside the fire-door A, said pipe being preferablycovered with firebrick or other suitable substance which will conductthe heat, but not allow the pipe to burn. The chambers E and F are alsoconnected by an opening, 0, in the partition dividing the same, and inthat side of the pan A 4 which connects with the chamber F we arrange aninlet-opening, a, closed by a suitable gate, a a is the outlet-pipeleading from the 6 pan A, which can be closed by any suitable faucet.

Through the back wall of the fire-chamber B are arranged any desirednumber of separate flues L L, which pass through the cham- 6 her G andconnect with the smoke-chamber H.

In working our evaporator the sap is poured into the chamber G,preferably at the point G, and passes under and around the flues L andthrough the opening 9 to the chamber C; thence through opening 0 to thechamber E, through the pipe K; from the chamber E, through opening 6,into cham ber F, from which it can be admitted at will through theopening a to the main pan A, from which the sirup or liquid sugarv canbe withdrawn, when required, by the outlet-pipe a It will be seen thatby our invention the sap is exposed to heat from the fire the momentitis poured into the chamber G, the back wall of the fire-chamber and theflues L L being in immediate contact therewith, and as it passes fromone compartment to another it is sure to boil to the required intensitybefore reaching the sugaring-off pan A, which is also exposed to thefiercest heat'from the same fire, the flaring or inclined sides a aaiding its concentration on the bottom of the said pan.

The lines L may be increased or lessened in number to suit differingrequirements, and the 0 smoke-chamber H is preferably made remov= ableto allow of the ready access to said dues for cleaning purposes, 85c.

Rings or handles m m are provided to render the apparatus more portablewhen required. 9 5 4 If desired, the outer chambers may be built roundwith brick; but we preferably make the whole apparatus of tin, as wehave found this material suitable in all respects; but we do not confineourselves to its exclusive use; neither do we limit ourselves to theprecise details of construction or number of chambers specified, so longas the essential features of our invention are preserved.

What we claim, and desire to secure by Letters Pateu t, is as follows:

1. In an evaporator,,the combination, with a suitable fire-place and themain or sugaringotf pan arranged above said fire-place, of additionalchambers or compartmentssituated around said pan and fireplace, so as tobe acted upon simultaneously by the same fire, said compartments beingconnected with each other, and arranged substantially in the manner andfor the purposes specified.

2. In an evaporator, the combination, with the main pan A, chambers U,D, E, F, and G, and fire-chamber B, of the inclined walls a a, as andfor the purpose specified.

3. In an evaporator, the combination of the fire-chamber B,smoke-chamber H, sap-chamber G, interposed between the chambers B and H,and the damperless flues L L, connecting the chambers B and H andpassing through the chamber G, substantially as and for the purposedescribed.

4. In an evaporator, the combination of the fire-chamber B, removablesmoke-chamber H, sap-chamber G, interposed between the chambers B and H,and the damper-less fines L L, connecting the chambersB and H andpassing through the chamber G, substantially as and for the purposedescribed.

5. The combination, with the fire-chamber B and sap-chambers D and E, ofthe connecting-pipe K, as and for the purpose specified.

Bury, the 1st day of August, 1882.
